private class SurfaceTool from GeomLProp
uses Pnt from gp,
Vec from gp,
Surface from Geom
is
Value(myclass; S : Surface; U, V : Real; P : out Pnt);
---Purpose: Computes the point <P> of parameter <U> and <V> on the
-- Surface <S>.
D1 (myclass; S : Surface; U, V : Real; P : out Pnt; D1U, D1V : out Vec);
---Purpose: Computes the point <P> and first derivative <D1*> of
-- parameter <U> and <V> on the Surface <S>.
D2 (myclass; S : Surface; U, V : Real;
P : out Pnt; D1U, D1V, D2U, D2V, DUV : out Vec);
---Purpose: Computes the point <P>, the first derivative <D1*> and second
-- derivative <D2*> of parameter <U> and <V> on the Surface <S>.
DN (myclass; S : Surface; U, V : Real; IU, IV : Integer)
returns Vec;
Continuity(myclass; S : Surface) returns Integer;
---Purpose: returns the order of continuity of the Surface <S>.
-- returns 1 : first derivative only is computable
-- returns 2 : first and second derivative only are computable.
Bounds(myclass; S : Surface; U1, V1, U2, V2 : out Real);
---Purpose: returns the bounds of the Surface.
